AUTOMOBILE CONTROL MECHNI SM Filed ApIil 22, 1927 INVENTOR PGE/DEH( mw y ATTORNEYS narran saar rarer carica y I rana a. am. orA more My invention relates to improvements in* automobile control mechanism, and it consists in the combinations, constructions, and arrangements hereindescribed and claimed.

An vobject of my invention is to provide an automobile control mechanism by means of which the motor is automaticallynusedas 'a service brake through the operation .of the usual control leversin theusual manner.'

A further object of my invention is tov ovide a device of' the type described w ich" saves on gasoline and reserves the brakes .for

emergency use, thus eliminating the wear and tear thereupon. This ellminates the burning of the brakes during steep or mountain drivfurther object of my invention is to provide a device of the type described which requires less ener y in driving, especially through city tra.

A further object of my invention is to rovide a device of the type described w ich automatically equalizes the brakes through the dierential which eliminates carbonication in the motoras the motor carbonizes when idling, and the idling of the motor is reduced to a minimum.

Other objects and advantages will appear in the following specification, and the novel features of the invention will be articularly pointed out in the 'anpended claims.

My invention is illustrated in the aeconb panying drawings, forming part oi this application, in which Figure l is a diagrammatic view of an automobile,

Figure 2 is a diagrammatic view embody ing my invention, and

Figure 3 is a side elevation of a portion of an automobile embodying my invention.

lin carrying out my invention, 'i make um' of an automobile having a motor i, a carburetor 2 and an accelerator 3. The accelerator 3 is provided with a contractile spring t for normally holding the accelerator away freni the floor board 5. The carburetor 2 is provided with a buttery or throttle valve 6 which is adapted to completely close a passa eway 7 vin the intake pipe d. The acce erator 3 is operatively connected' te the vaive 6, by the usual' means shownin the form of a rod 9.

l rovide an accelerator-actuating arm 10 whic is pivotally mounted at 1l u on any suitable support such as the oor oard 5. The freeuend of' the arm 10 is operatively connectedto the accelerator 3 in any suitable inanner, such as by a pin 12. l

A clutch ,edal 13 is similar to the ordinary clutch poda with only one exception and that is the provision of an actuating cam i4. rl.`he cam ld is made integral with the clutch pedal i3 and is provided with a tapering surface l5 disgosed adjacent the arm 10 when the clutch pe al is in normal position. A brake pedal lo is simiiar to the ordinary brake pedal with only one exception and that is thc'provision of a shut-od cam 17 which is relatively large in cross section adjacent the arm 10 when thev f brake pedal is in normal ostion. The shuted cam 17 tapers inwar y from a point adjacent the arm 10 'when in normal position,

From the foregoing description of the various parte of the device, the operation there of' may be readily understood. Let us assume that the automobile is in motion and that the driver wishes tostop the automobiie. lln doing so, the operator presses upon the brake pedal 16 in the ordinary manner in which to apply the brakes. Before the brake pedal is moved a sucient distance to apply the brakes, the enlarged portion of the cam 17 is moved away from the arm l0 aliowing the rin 4 to move the accelerator` 3 outward y, t us actuating the valve 6 so-that it will completely cut o communication between the carburetor andthe intake manifold. By so doing, the fuel is cut od @om the motor and as the motor is operativeiy connected to the diierential and the rearl wheels of the automobile, the motor serves as a braking means. due to the fact that the rear wheels, torotate, must actuate the motor. This braking means is suilicient to stop the momentum of the automobile within a relatively short distance from a moderate rate of speed. If the automobile is traveiing at a relatively fast rate of speed and the driver unexpectedly is required to stop the momentum of the automobile withn wardly againstjthe tension of the spring 4 and moving the valve 6 again into idling po# sition. v after Athe valve 6 is openedto idling position and before the clutch is disengaged is suficient to again startthemotor actuating. By continued movement of the clutch pedal, the clutch is disengaged in the usual manner and the operator may shift into neutral until he is against ready to start the movement of the automobile. i

When the automobile is stopped, the brake pedal 16, together with the clutch pedal 13,`

is released and allowed to move into their normal position. `During the movement of the pedals into their normal positions, the

cam 17 is moved into engagement With the arm 10 as the cam 14'is moved out ofengagement therewith. i

It is obvious that the cams 14 and 17 may be provided for a clutch pedal and a brake' pedal of any type and used upon any type of automobile for producing the same result f Without departing fromthe spirit and scope of the invention.
